HEAT INSULATED BOTTLE CONTAINER Filed OGL. 19, 1939 1111111111114vIIIIIHIn/IIII Patented June 17, 1941 UNITED STATES PATENT OFFICE HEAT INSULATED BOTTLE CONTAINER Edgar Alvin Wckstrom, Marquette, Mich. Application October 19, 1939, Serial No. 300,269

2 Claims.

This invention relates to a container and it aims to provide such an article as utilizes the insulating properties of dead air space especially in corrugated board, the containerbeing especially adapted for the reception of an infants feeding. bottle when the mother is visiting or motoring or at night and is also useful for packing hot and cold foods fer. picnics, outings and the like.

Various other uses, advantages and objects will become apparent from a consideration of the description following taken in'rconnection 'with accompanying drawing illustrating an operative embodiment. I

Figure 1 is a view of the container in central vertical section; i

Figure 2 is across sectional view taken on the line 2-2 of Figure 1;

Figure 3 is an enlarged longitudinal sectional view of an upper portion ofthe container and closure, better disclosing details, and.

Figure 4 is an enlarged longitudinal sectional view of a lower portion of the container and bo't-. tom, to better disclose details.

In carrying out the invention, the container has a generally cylindrical body as' at I0. This body consists of a number of layers or sheets, for instance three, of corrugated pasteboard or the equivalent, each sheet being endless or cylindrical. At the inner and outer surfaces of the sheets, they are joined by `paper sheets II, impervious to air, the outer one ofwhich is preferably stiffer as shown and extended or continued downwardly below the same as at I2.

Said portion I2 is extended inwardly and upwardly forming a wall I3. y The wall structure for the bottom of the contalner is substantially similar to that of the side pressed or beaded into the same as at I9. 4 fr disks 2I on both sides of which are sheets of paper 22 impervious to air. Between the innermost sheets 22, is a stiffer sheet or disk of paper 23, having an upwardly extending annular wall 24. An outer annular Wall 25, removabl g slides over the upper end of the container Ill, ith the lowermost sheet 22 engaging the ends of the various walls thereof, closing the air spaces of the corrugations. Said wall 25 is turned inwardly at 26, over the upper end of the wall or flange 24, having a marginal flange 2l, engaging the upper wall 22 and the flange or wall 26 preferably being beaded as at 2B into the flange 24. Obviously, all of 'the parts ofthe removable closure 20 are connected together in any suitable manner as by means of an adhesive.

Closure 2|] may be readily removed in order to place a bottle, foods ror the` like, within the interior of the container I0 and then replaced and the parts may be darried against danger of leakage, formation of frost on the exterior, or the same becoming' too hot, and without any other disadvantages. f

Various changes may be resorted to provided they fall within the spirit and scope of the invention. i :f

I claim as my invention: l

1. An insulated container of the class described having an outer cylindrical wall provided with an interior annular returned portion at one end, an end wall disposed inwardly of said end having a marginal flange disposed between saldf re. turned 'portion and cylindrical wall, corrugated Walls disposed in the space 'between said end wall and ond of the cylindrical wall, and means also in said space to support the corrugated Walls and seal the space containing them, and hollow wall means Within the cylindrical wall having end contact with said end wall. if

2. An insulated container having a cylindrical wall, 4corrugated walls interiorly thereof providspaces, a closure having an outer cylindrical wall slidably applicable over the rst men- All of the parts mentioned of the cylindrical? wall or body Ill and the bottom closure I4, are securedtogether in any suitable manner usually by means of an adhesive.

The top of the container is in the form of a removable closure generally designated 20. This tioned cylindrical wall, said second mentioned CY- miV i 4.

lindrical wall having an inner returned portion at the top thereof, a tcp wall within the second mentioned cylindrical wall having an upwardly extending marginal flange `disposed between said returned portion and second mentioned cylindrical wall, means below the top wall to extend over the corrugated walls to close the air spaces thereof, a sealing member across the closure in abutment with the lower edge of said returned portion, and corrugated wall nieans between saidl top wall and said sealing member.
